Comment 8 for bug 1841592

Dave ran the above testcase on:

> processor : 0
> cpu : POWER8E (raw), altivec supported
> clock : 3325.000000MHz
> revision : 2.1 (pvr 004b 0201)

And there are no diffs with what you currently get from master. So I think the invalid flag fault is fixed by a previous commit and the potential precision faults don't get picked up by the test case. I guess we could be a bit smarted about testing the limits.
